Brand New Genuine Ford MK6 Fiesta 

Rear Lamp Outer Fixing Clips x 4

These Clips fit all MK6 Fiesta Models from 2002-2008

2 Clips required per side your Rear Lights should be fitted almost tight to the bodywork not with big gaps as shown 

TIP: Fix the Clips to the Metal Pins on the Rear Lights first fully pressed on, then go to fix the Light to the car putting the Top White Clip into position first then the lower Black Clip then press them both (Firmly) into the holes in the bodywork. 
If they have located properly you should have no more than a 2-3mm gap between the Light and the bodywork. If you look under the Black Clip you will notice 2 tiny locator tabs which need to go fully into the bodywork to make the Light fit properly.
